R31 must be depopulated to power module using V+ and GND from J2 and J5. Sense lines can be connected to S+ and S- for sensing power supplies. CAUTION: Voltage not regulated. Applying incorrect voltage can cause fire and serious injury. See Note 1. SPI Power Connect to power board from 3.3V Current Testing Depopulating R31 allows a current probe to be inserted across P6 terminals. The current though P6/R31 powers the module only. Other supporting circuitry is powered by a different trace. Reset button Loopback Jumper Populating P8 with a loopback jumper causes transmissions both from the module and from the USB to loopback. DC barrel plug: 6-20V Module can be powered by the USB or DC supply. When plugged in simultaneously the DC supply powers the board. Indicator LEDs DS5: ON/ SLEEP User Buttons Connected to DIO lines for user implementation LED Indicator Yellow: UART Tx, RF Rx Green: UART Rx, RF Tx Red: Associate RSSI Indicator USB NOTE 1: Powering board with J2 and J5 without R31 removed can cause shorts if USB or barrel plug power is connected. Applying too high of a voltage will destroy electronic circuitry in the module and other board components and/or cause injury.
